Equation for calcuating the weight of a pipe pile per foot:
	Non-Metric:  (OD - wall thickness) x (wall thickness) x 10.69  = lbs per foot
		Example for 30 inch pipe piles with a 1/2 wall thickness
		30 - .5 =  29.5  X  .5  =  14.75  X 10.69 =  157.677 lbs per foot

	Metric:  OD(Outside diameter) in m x 3.14 x wall thickness in m x casing
		length in m x density 7.8
			
Equation for converting Foot-Pounds to Joules:
	Multiply the foot-pounds by 1.356

And the reverse - Joules to Foot-Pounds:
	Multiply the joules by 0.7376
